Application led June 25, 1915. Serial No. 36,196.

To all whom it may concern Be it known that I, JOHN A. BLioHMANN, a citizen of the United States, residing at Dubuque, in the county of `Duhuque and State of lowa, have invented certain new and useful Improvements in Apparatus for Operating Flush-Tanks, of which the following is a specification.

My invention relates to. means for operating flushing devices such as water closet bowls or basins, in which is a siphon or in iiushing a bowl direct from the water supply without a tank and which has special reference to the position of the valve and the means whereby the valve operates the Siphon and co-ntrols both the intake and discharge of the water even when there is no tank.

A further object is to remove all working parts that control the discharge or refilling of the tank entirely outside of the tank, where they can be readily gotten at to repair. Further to start the siphon and refill the tank and this jet controlled by means outside of the tank, and nothing in the tank except f the siphon and jet.

In what it consists its mode of construction and manner of operation will be fully set out in the following specification and illustrated in the drawings accompanying the same and forming4 a part hereof.

Figure 1. is a vertical section of the tank when filled and a side elevation of the operating valve. Fig. 2. is a vertical section of the tank when it has finished flushing the basin and nearly empty. Fig. 3. is a sectional view of the valve for controlling the water. Fig. 4. shows a perspective view of the closet basin without a tank and a perspective of the controlling valve. Fig. 5. is a sectional View showing operation of lever and self closing valve. Fig. 6 is a sectional View showing needle point valve controlling supply of water in diaphragm chamber.

Like characters of reference denote corresponding parts in each of the drawings.

My improvement is intended to do away with the numerous parts and with the noise, madein flushing tanks by means of usual valves with water supply running direct into the open tank and commonly controlled by fioats andoperated by levers or chain pulls of some kind in or about the tank. Further to do away with all operating-parts in the tank except the stationary Siphon and entirely through a jet in the tank,

jet pipe leading into it, thereby making it as simple as possible with the desired effect. "The valve when used without the tank is ldentical except that'it is made larger so as to have necessary water supply to tiush the bowl, which is not necessary when it has the assistance of the water in the tank in flushing the same.

Having reference to the drawings 2 designates the tank, 4 the discharge member of the siphon and 5 the intake member. At the .top of 5 it ismade slanting at 3 for the purposes presently to appear. Through the side of the intake member 5 projects a jet 6 which is directly connected with the water pipe 8 that enters the valve l0 at its base and the supply pipe 12 from the main, enters the said valve 10 at the top of the valve.

The valve l() is provided with' numerous chambers 15, 16 and 1T. The chamber 16 is connected to the main water supply by the pipe 12, the chamber 16 is connected-with the diaphragm chamber 15 by a passage wav 20 which is controlled by a small needle `point valve Z2 as in Fig. 6. The chamber 15 is closed from the balance of the valve 10v by a diaphragm 24 and bv an automatically closing valve 25 as in Fig. 5 which is opened by a lever Q6 that projects through the casing 28 of the valve 10 as shown in Figs. 1 and 4.

Near the center of the valve 10 is set an operating valve 30, -which consists of a head 32 that presses against the diaphragm 24 and a stem 34. On the stem is secured a member 35 of cup shape in which is secured In the partition 29 upon one side ofthe chamber 16 is an opening and the edges 40 of bthe partition are bent inwardly around the opening and form a seat 42 for the valve 30 and against this seat rests thev packing. 36. The stem 34 of the inner valve 30 is screw threaded at 44 and upon this is screwed a member 45 carrying guides 46, whereby the valve 30 is always guided off from its seat and back onto its seat and prevented from tipping in any direction. y

The manner of operating is substantially as follows: The operator grasps the lever 26 and pulls it down and this allows the water in chamber 15 to pass out into chamber 17. The chamber 15 then becomes practically free water in chamber 16 will unseat the valve 30 of water, and the pressure of the' and push in the diaphragm 24 andthe Water will flow over the seat 42 into the chamber l? and through the pipe 8 up and out of the jet 6 and as the tank 2 is nearly filled with water it will quickly fill the memberp and start and flush the bowl or basin and continue to do so until the water in the tank is below the open end of the member 5 of the Siphon, when the air will enter the member and close the Siphon, but the water will continue to flow through the jet 6 striking against the slanting top 3 and falling back into the member 5 until the tank is filled nearly to the top of the jet. At the same time the water from chamber 16 will flow through the passage way 2O until the chamber 15 is filled and then the pressure of the water against the diaphragm will reseat the valve 10 and thc flow of water from the supply will cease, but when properly adjusted by valve 22 as in Fig. 6 the valve, 10 will not be seated till the tank is filled to a point 47 as shown in Fig. 2 below the top of the jet pipe 6 or in case the valve is used without tank as in Fig. 4 the valve 30 will not be seated until plenty of water has been allowed to pass through the valve to properl flush the bowl.

Isl: will be seen by the foregoingt'hat there is nothing in the tank except the Siphon and the jet, and all of the water for starting the siphon and refilling the tank is obtained through the jet, while the means for controlling the water is wholly outside of the tank or outside of the fiush bowl. where it can be gotten at to repair with little or no trouble and nothing in the* tank to get out of repair.

Having now described my invention what I claim is:

l. In a device of the character described, a flush-tank, a Siphon in the tank, a jet terminating in the tank, and means outside of the tank and connected to the jet for starting, the siphon to from the tank and refilling the tank through the jet. 2. In a device of the character described, a flush-tank, a siphon in the tank, a jet terminating in the tank, a valve outside of the discharge the water tank, and means connected with the valre for starting the siphon and refilling the tank through the jet.

3. In a device of the character described, a Hush-tank, a Siphon in the flush-tank, a jet in the tank, a valve outside of the tank for controlling the water through the jet to operate the Siphon for flushing the bowl, and for controlling the refilling of the tank through the jet.

4. In a device of the character described ay fiush-tank, a siphon in the tank, a jet in the tank and emptying into the Siphon a valve situated outside of the tank for opere ating the Siphon and refilling the tank through the jet, said valve having therein a `diaplfiragm for controlling the flow of water into the tank through the jet.

5. In a device of the character described a Hush-tank, a siphon in the tank, a jet terminating in the siphon through which all the water is supplied to the tank, a valve connected with said jet and with the water supply, and means within the valve for con trolling the water supply to the jet. 6. In a device of the character described, a flush-tank, a siphon in the tank, a jet in the tank, a valve outside of the tank and connecting the water supply with the jet, a diaphragm located in a chamber in the valve With a valve at each end of the chamber for controlling the water supply through the jet to the tank.

7. In a device of the character described, a flush-tank, a siphon in the tank, a jet in the tank, a valve outside of the tank and connecting the water supply with the jet said valve provided with three chambers, a diaphragm in one chamber with a valve at each end of the chamber, a valve connecting two of the chambers and said valve operated by said diaphragm to control all of the supply of water to the flush-tank through the 3er..

In testimony whereof I afix my signature in presence of two witnesses.
